Be it known that I," ELOY Rooiirerinz,A a" citizen of the United States of America? residing at Fajardo, Porto Rico,'have invented certain ynewA andluseful improvements in Oil-Burners', of which the follow-V ing is a specification. Y

The present invention has reference to burners adapted tor `heused with liquid fuel, such as crude oil.l f

,"Nitli burners of thisy nature it is" often*` difficult to produce an'eiiicient combustion owing to the fact that v the liquid does notV readily atomize and also that thevfuel noz,- zle becomes clogged with an accumulation of solid material contained-in the oil.y

. One of the objects of this invention is to providefa burner in which the liquid fuel prior to 'its discharge to be atomizedfb'y the action of lsteam whereby thecoldoil, will be" prevented from overflowing the ynozzle inv consequence'of which leakage will 'be -prevented and a constant pressure and efficient flame obtained.

Another object of my invention is vtoco'n'- Astruct the burner so that thick oil when used as fuel on entering the burner will be broken up into small particles soV that its flow through the burner will be continuous.A

Another object of this invention is to provide a burner which can beV readily cleaned without removing the burner and discon l nerting it from the oil and steam supply Pipes# f It is a further object of my invention to provide such -a yconstruction which vwill en-A able 'its application to 'any'kind of boiler furnaces, eithermarine or land. Y

And still'al further object is to `construct the fuel burner of lbut a few parts thereby greatly simplifying and cheapening the burner.

lrVith these and other objects 4in View, my invention consists in the combination, construction and arrangement of' parts as hereinafter more fully described and set forth in the appended claims. l In the accompanying drawing in. which similar 'reference characters denote 'corre'-v sponding parts, Figure 1fis a sectional view of the yoil burner; Fig. 2 is a longitudinal section'on line 2-2 of Fig. 1; Fig. 3 'is a cross section on line 3 3 of Fig. 1; Fig. *4fV is a front view ofthe oil burner witha part broken out; Fig. 5 is a front view of an intermediate section of the oil burner; Fic.'

6 is a; similar viewa'sFigl of a somewhat modified construction.;v Fig. 7 is a similarv section as Fig. 2 ofthis modifiedconstruction; ig.. 8 is ax front view thereofand Fig; 9 isa longitudinal'section ofthe' .frontV part kof thel burner.y f

' Referring `specifically to the drawing, andfirst to the construction shown in Figs.

1-5", the' oil burner vis composed' of several I sections' to wit.: 15 2,'3,'and 4, which vare .removably jointed together so that for cleanving or other purposes the-sections can be easilytaken apart without disconnectingv thedevice' from the supply pipes. As will be seen from the drawing the base portion or section 1` of theburner is provided with two lateral threaded bores.' 11 lgjextending longitudinally throughth'e body and 4paral? lel to. oneanothen Theborel1 serves for the attachment of the V'supply pipe for steamH and terminatesiin 1a substantially Zi'shaped groove which is complemented .by asimilarl groovejprovided inthe interme-l diate section 2te form asub'stantially-conical steamy pocket 13. a circular passageV 211,1 nade in the intermediate disk shaped section 2 and1owingto its. shape is' adapted :to gradually compress the steam 'before the latter passesinto the chamber 31." 'l`he1boref12 vserves "for they attachment of the supply pipe .(not shown).

for crude oil and terminates in a passage` 14 leading into a cylindrically curved cham j* ber 22. The chamber 22 extends laterally from said passages'l4 Vandy its walls are so and thereby retarder, inf consequence vof of a truncatedv cone, and 4is formed with av central cylindrical' chamber 31 into which y8() i 'This pocket leads into l form-an obstructiona'whereby 'i the oil flowing into the chamber through the oil inlet will be deflected-from Aitscou-rse'` which'the loil contained inthe chamberwill i 'be'more effectively heated.l

the'steam is allowed to accumulate through the central "passage'21 from the supply pipe tion which are arranged' close tov one auf' other and whichlead from the bottoni ofthe leadingv into the passage` 13. Extending 3 are a plurality of 'ilon-y I wall opposite the inlet '12of 'the chamber 22, y

or are arranged in such relation to said wally that the oil flowing into said' oilchamber will Ybe deflected fromits straight course by wall and prevented thereby from passing# 32 are separated hy a comparatively thin y wall from the steam chamber 31 so that the tion .tions 1 Vand 3 with steam accumulating in the latter will heat Vthe oil flowing through the passages 32 and maintain it in liquid state.

The chamber`31V andpassages 32 do not extend to the front end of the section 3but terminate inside said body. The chamber 31 is closedby a convex dome'32. J ust beyond the said dome 33 segment ofthe section 3 is cut away so that thebase of said segment is a horizontal plane about even with the.

longitudinal center line of the chamber 31 of said segment and the rear wall thereof is a vertical plane coinciding with the top or front, wall of the dome 33 and the front' open ends of the passages 32. Cut. transversely in said wall is a horizontal slot 34 which constitutes thel egress or mouth of t-he chamber 31. In .thev horizontal wall 37 a groove' 39 is provided the lateral walls 312 of whichdiverge forwardly from'the cornersl ofthe mouth34 (.Fig. 2).

T he segmentalportion cut away from the body 3 forms the section 4 of the four sectioiis composing. the burner. This segmeutal section 4 is provided with a groove 41 at its lliottom ksurface and at its vrear with a groove 42,7so'that when the parts are assembled the groove 41 forms with the groove 32 the nozzle n, and the groove 42 forms a duct for theioil leading into said nozzle.v

rheiiioii'th opening 34 is partly obstructed-by a member 'which is counter-k su-nlr iii-the front wall 36 of the section 3 and by screw bolts 6 is secured to the latter.VV

The lower end or lip 51 of the member is curvedr :forwardly projecting into the nozzle n. The section 4 is removably secured to section 3 by screwbolts 7 or other suit' ablemeans.

To hold the different sections together lV provide the following construction:

The base portion 1 isvformed with diametrically opposedeyes 1, each .provided with a threaded bore 17.` The body or sec- 3 has at its rear end. an annular en-I largement forming a shoulder 312. Cylindrical sleeves 8 each formed at one end with a lateral projection or nose S1 serve'asr clamp members. The latteiareadapted .to loe placedagainst the eyes 1G and toenga'ge with their noses 81 the shoulder 310. Loosely borne in the sleeves 8 'are bolts 9 which at and adapted ATo reproduce a tight jointA between. thesections l? 2 and 3 and to guardsection 2 against displacement, section 2 is provided on its rear and front faces with grooves 23,

Y 2t, adapted to engage annular flanges 15 and 3; formed on the sectionsl and 3 respectively. Y l Y rEhe mode of operation ofmy burner is Vvas follows After the sections of the burner have been properly assembled and the burner is positioned inthe furnace of the locomotive or the like, the supply-*pipes (not shown) are screwed. into the bores 11y and 12, Steam flowing through pipe l1 accumulates in the steam chamber 3lv and heats the oil which so accumulates in the chamber 22 and thence passes into the different'vpassages 32. While flowing through the latter thev oil is continuously heated by the steam contained iii the chamber 31 andis thereby maintained in liquid state. Emerging from the chamberV 31 through the mouth 34 the steam is thrown upwardly bythe wall 37 and unites withthe oil emerging from the passages 32 and vflowing down the passage 41 whereby the fuel particles will be broken up and become. atomized before it passes outwardly through thenozzle n. At the saine time the steam shooting through the nozzle n will remove any foreign body accumulating'in the nozzle n and prevent thereby thev clogging fof the latter.`

The above described burner Ais adapted for use on. small locomotives or the like.

Forhiggerlocomotives Iprefer to employ 100 the construction. shown in Figs. 6-9, which in principle is the same as the first described burners, but differs from the latter aside from size also in certain particulars'toY be'. presently described.l Y

In this modificzuzion the burner is composed of five sections instead offour, to wit, 'the hase o, an intermediate disk shaped section 7i, a cylindrical section c, aconical head d and a` segment shaped sectioncf The secf tions ci, Zi and c are `ioined together-by screw bolts 7 instead of by the clamps used in the first described.construction. Y The front end c1 of the cylindrical section@r is-'somewhat reduced in diameter and Vscrewy threadedpil and adapted to he screwed into a threaded bore ,d1V of .the conicaljhead d. Y

The oil. passages gvarranged in an arc around the Steamchamber 7b provided in the cylindrical section c infront terminate in ducts or passages d2 provided in the' head piece d and lead into a Vcommon passage z' formed by the segment e. 'The tongue y" which is arranged iIi f front of the slot or mouth h1 of the steam chamberandwhere-V bv the quantity kof lste'ain issuing from the chamber and passing into the nozzle n is adgustablv secured to the head d byxproviding it with oblong holes jl through which l the 'fastening screws 7c: are passed. rais-*130 ing or 'lowering the tongue y' the passage between the lip jz of the tongue "j can'be 1n- Y creased or reduced.

The operation of this modified burner is the same as that of the first described construction.

The advantage of my over those hitherto in use, is, stated, that it permits the burner ily taken apart without requiring its disconnection from the supply pipes' and its re-A moval fromthe furnace.

burner construction The divisional lines of the different sections are so selected that the passages and chambers therein when the sections are taken apart are accessiblev for cleaning, and inspection as to the cause of interruption of -the flow of the fuel when this occurs.
